WHY?

Windspot resolves the three traditional problems of small wind power: low productivity, poor reliability and noise.


  1. Our wind turbine begins to produce energy with very gentle winds (2.5 meters per second) and does not stop working at maximum performance even when winds reach high velocities (more than 25 meters per second).
  2. Moreover, Windspot is a robust, reliable and hard-wearing, wind turbine, with a useful life of at least 25 years and low maintenance requirements.
  3. A noisy turbine can be unbearable company. At Sonkyo Energy we have worked to the point of making Windspot into one of the most silent turbines in the market.


A combination of technology, design and quality makes Windspot different

Get to know the advantages of our system:

Variable pitch. A technology patented by and exclusive to Sonkyo
  • It is a passive mechanism that uses the centrifugal force produced by the  turning of the wind turbine to change the attack angle of the blades, which adjust themselves in a synchronized movement, cushioned by a hydraulic cylinder, to the strength of the wind.
  • Variable pitch provides higher productivity and reliability. Thanks to variable pitch, an excess of revolutions is avoided that would damage the generator and means that Windspot continues working at maximum performance even with high wind speeds.
  • To protect themselves from the strongest winds, other turbines activate protection systems that, paradoxically, slow up their production when the conditions to produce energy are at their best.

Aerodynamics of the blades
  • The aerodynamics of the blades allows the wind turbine to begin to produce energy with very low wind speeds. Windspot begins to work from 2.5 m/s
  • The exclusive aerodynamics of the blades developed by the Sonkyo Energy research department results in a smooth and silent turn.

Windspot works at low revolutions
  • Windspot is designed to work at low revolutions. Our wind turbine does not exceed 250 rpm (WINDSPOT 3.5) while other turbines reach 1000 rpm. Low revolutions result in less noise without affecting energy production.
  • Mechanisms that work at low revolutions reduce fatigue on materials and have a lesser risk less of suffering damage.

High qualities of design and manufacture

Windspot is a wind turbine manufactured with the best materials. 
  • Windspot is manufactured from stainless steel, anodized aluminium and bronze.
  • The turbine is protected against corrosion, dust and water.
  • The low weight of the blades, manufactured form polyester and fiberglass with RTM technology (Resin Transfer Molding), means that the turbine suffers less wear and tear, reducing maintenance to a minimum.

Permanent research and development
  • Windspot is a wind turbine which is a result of 30 years of research.
  • Our R & D department works to achieve more productive, increased reliability and quieter turbines.
